The rear trunion that comes on a Draco is actually quite strong. The trouble is that it does not come with the attachment point for a stock. You have to replace it, which involves some cutting and welding.
The Draco has a few things going against it. Foremost is that it is a pistol! Making it an SBR requires a $50 folding stock (may as well keep it short), a $15 rear trunion, $100 (guessing) replacement job at a gunsmith, and a $200 tax stamp. This makes your $400 novelty into a $800 rifle with no good mounting point for optics and a short sight radius on open sights.
If you must have the short barreled AK, go for it. But if you can stomach six more inches of barrel, you can get one ready to go for $500. Longer sight radius, no waiting 6 months for BATFE, quite a bit cheaper.
Put a sling on your Draco and learn to fire while putting positive pressure forward. You can either dremel the grip or add a sling plate between the grip and the receiver. Either works fine. I routinely post 4-5" free standing groups at 25y with the stock sights, and have (with slow fire) put down 2-3" groups. With optics or more practice, I think I could get there consistently.
